Place: Bar-Ilan university,Israel
(*) with an option of long stays at Göttingen, Germany.

Detailed description: We are looking
for one or more post-doctoral researchers in mathematics. The two main projects we are
interested in have to do with probability on groups, however
researchers in most areas of probability are encouraged to apply and we
may also pursue other research interests.
Two suggested projects
1. Geometric exponents of random walks on
groups - i.e. what are the possible behaviours of speed,
entropy , return probabilities etc.. of random walks on groups. What
are the relations between such quantities and other group
properties etc.. and
2. Extensive amenablity, group actions
and inverted orbits. - the study of amenability and
Liouville property of groups via their actions (and Schreier
graphs). We will be happy to describe these in more detail.

(*) Part of the funding comes from a
joint German-Israeli foundation grant with Prof. Laurent Bartholdi. It
will be possible to do parts of the post-doc at Bartholdi's group in
Göttingen. Funds will be available to cover travel costs and the
higher cost of living while there.

Benefits: Job is academic with a
competitive salary and no teaching required. Other top Israeli
institutions such as Tel-Aviv University and the Weizmann Institute are
nearby and interaction with them during the post-doc can be very
beneficial.

Duration: The position is for up to
2+1 years, though time-length and starting date are flexible.
Short-term applications for periods as short as 3 months will also be
considered.
